Combining Very Large Quadratic and Cubic Nonlinear Optical Responses in Extended, Tris-Chelate Metallochromophores with Six π-Conjugated Pyridinium Substituents

Coe, Benjamin J.; Fielden, John; Foxon, Simon; Brunschwig, Bruce S.; Asselberghs, Inge; Clays, Koen Jan; Samoc, Anna; Samoc, Marek


We describe a series of nine new complex salts in which electron-rich Ru" or Fe" centers are connected via jr-conjugated bridges to six electron-accepting N-methyl-/N-arylpyridinium groups. This work builds upon our previous preliminary studies (Coe, B. J. J. Am. Chem. Soc. 2005, 127, 13399-13410; J. Phys. Chem. A 2007, 111, 472-478), with the aims of achieving greatly enhanced NLO properties and also combining large quadratic and cubic effects in potentially redox-switchable molecules....[Show more]
